VENTILATING-COVER FOR MILK-PANS.

SEBGIFICATIQN forming part cf Letters Patent No. 337,816, dated March 16, 1886.

Application led December 14, 1885. Serial No. 185,681. (No model.)

To @ZZ whom t may concern:

Be it known that I, JAMES Dnvins, a citizen of the United States, residing at Mitchell, in the county of Davison, Dakota Territory, have invented a new and useful Improvement in Ventilating-Covers for Milk-Pans, of which the following is aspecitication, reference being had to the accompanying drawings.

This invention relates to ventilatingcovers for milk-pans, pails, cans, and other open vessels, and has for its object to provide a device of this character which shall exclude insects and iiying foreign substances of every description from the vessel, and at the same time allow a free circulation of air over the surface of the milk, and also prevent the water which condenses on the inner surface of the cover from falling back into the milk.

With these obj ects in View the said invention consists in the peculiar construction and com` bination of parts, as will be hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of a milk-pan with my iinproved cover fitted in position thereon. Fig. 2 is a similar view illustrating the attachment of my cover to a milk-can. Fig. 3 is a longitudinal section taken centrally through Fig. l. Fig. et is a detached side elevation of a portion of the perforated wall. Fig. 5 is a detail view illustrating a modification.

Like letters are used to indicate corresponding parts ofthe several figures.

Referring to the drawings, it will be seen that my ventilatingcover comprises, essentially, a sloping top, A, a depending circular wall, B, and ahorizontal base or rim, O. These parts are constructed of three separate pieces of tin or other sheet metal, the wall B having its upper and lower edges soldered or otherwise secured to the top A and the base or rim C. The wall B is secured to the top some distance inward from its outer edge, so as to form a projecting flange, a, on the top, which will extend beyond the wall, so that should any water iind its way on the top A it will be prevented from obtaining access to the interior of the vessel through the perforated wall B, since the iiange a serves to carry off the water beyond thelatter. The wall B may be made entirely of perforated sheet metal, or, as shown in the drawings, of imperforate metal having holes cut through the same at suitable intervals, as at b, these holes being covered with wire-gauze or other open-work material,either construction effecting the desired end by securing a proper degree of ventilation, though for practical purposes I prefer the construction shown in the drawings. nection with the top A and base or rim O, the wall B is notched or cut out at regular intervals, as at E, to forni openings when the wall is secured in position, these openings E permitting the passage of the water which condenses on the inner surface of the sloping top A, and thus preventing it from falling back into the milk. The lower edge of the'wall B is secured at some distance inward from the outer edge of the rim C, so as to leave the pro- 7e jecting flange e on the rim, as will be seen. This rim O,which forms the base of the cover, has on its under side, a short distance inward from the point of connection with the wall B,

an annular groove or depression, F, which is adapted to receive the upper beaded edge ot' the pail or can D, and thus support the cover in position on the pailand prevent lateral dis placement. ln lieu of this connection between the milk pail or can and the rim or base O of 8o the cover, I may secure by solder or otherwise on the outer face of the rim Ca U -shaped piece of tin, (shown at the point G, Fig. 5,) the beaded upper edge of the pail fitting within the strip G between its side walls and holding the cover thereon. It will be understood in both cases-t'. c. whether a groove, F, is formed in the base or rim or a strip, G, attached thereto-two parallel guide walls are provided,

in the space between which walls the upper 9o At the point of con- 6cv The rim or base O extends inwardly The peculiar curved roo ing E, enables the moisture' condensing on the inner surface of the top A to be carried off to each side and escape through the top openings at the junction of the wall B with the top A.

@Should any of the moisture escape beyond these openings down the inner surface of the wall B onto the rim or base C, this moisture would be carried out through the lower openings, E, at the base C, as will be seen.

In the use of this improved cover I do not wish to be coniined exclusively to vessels for containing milk, as it may be used for covering any other material requiring ventilation. The inner end of the rim Gis turned up or iianged, as shown. in Figs. 3 and 5, so as to prevent the water of condensation, should any reach the rim, from dropping down into the milk.

Having described my invention, 1 claim- 1. In a Ventilating-cover, the solid top A,

provided with the Ventilating-wall B, depending therefrom, and the horizontal base or rim C, projecting inwardly from its point of connection with the wall and resting on the upper edge of the vessel to support the cover, as set forth.

2. In a Ventilating-cover, the top A. having a flange, a, and provided with the wall B, having Ventilating-openings, and the base or rim C, as set forth.

3. A Ventilating-cover having the sloping top A, andv the Wall B, provided with escapeopenings E at the point of connection with the top, as set forth.

4. A Ventilating cover having the top A, the wall B, provided with escape-openings E at the point of connection with the top, and the base or rim O, as set forth.

5. -A Ventilating-cover having the top A, the wall B, depending therefrom and provided with Ventilating-openings, and the base or rim C, connected to the Wall and extending inwardly therefrom, so as to rest upon the 'upper edge of the vessel and support the cover, the wall of the cover being held away from the vessel, as set forth.

6. A ventilating-cover having the top A, the wallB, depending therefrom and provided with Ventilating-openings, and the base or rim C, connected to the wall, extending inwardly E therefrom and provided with two parallel guide-walls, in the space between which the upper edge of the vessel is received, as set forth.

7. A Ventilating-cover having the top A, the Wall B, and the base or rim C, said wall having suitable Ventilating-openings, and notches E, cut out of the wall at the point ofjunction withthe top A and base C, as set forth.

In testimony that I claim the foregoing as myown I have hereto affixed .my signature in presence of two witnesses.
